📚 Quick Study Guide

  • 🔥 What are Solar Flares? Solar flares are sudden releases of energy from the Sun's surface. They emit radiation across the electromagnetic spectrum, meaning they send out light, radio waves, and X-rays.
  • How Fast? These flares travel at the speed of light, so their effects can be felt on Earth almost immediately (about 8 minutes after they occur!).
  • 🛰️ Affected Tech: Solar flares can disrupt radio communications, GPS signals, and even power grids. Satellites are especially vulnerable.
  • 🧭 Auroras: Solar flares often cause beautiful auroras (Northern and Southern Lights) to appear more vividly. The charged particles interact with Earth's magnetic field and atmosphere.
  • 🛡️ Earth's Protection: Earth's magnetic field and atmosphere protect us from most of the harmful effects of solar flares.
